“I don’t know if it’s shocking,” Ottenberg said. “I’m with her all the time, so my shock gauge is off. But I told her that I thought she was ready for this dress a while ago, and that I wasn’t. I’m the prude, and I’m just catching up.”

He continued, "I did this look for her so she’d have a good time. This was the perfect night do to something fun, and I wanted her to have something great that you couldn’t find anywhere else in the world.”

Ottenberg also explained why they chose the designer.

"We wanted to do an American designer, and he was just the right choice,” he said. “He’s worked so closely with us, and so hard for us. He’s turned it out for her so many times, and we were excited to do this with him.”

The singer clearly liked the look, as judged by her celebration at the end of the night, captured by her hairstylist:
